User authentication is one of the features almost every app(web and mobile) needs today.
Techniques for authentication in AngularJS applications — Opinionated AngularJS. Authentication The most common form of authentication is logging in with a username (or email address) and password.

This means implementing a login form where users can enter their credentials. Such a form could look like this: <label for="username">Username:</label> <input type="text" id="username" ng-model="credentials.username">
AngularJS.DE → AngularJS - Login & Sicherheit. Nodejitsu joins GoDaddy. In 2010, Nodejitsu started with a simple idea: a company with Open Source in its DNA creating essential productivity tools focused on a new platform that most people had never heard of or were already dismissive of: Node.js.

Back then the server-side JavaScript ecosystem was fragmented and diverse; with CommonJS the only (barely) unifying thread between names like Narwhal, Rhino and Node. Yet despite the obvious challenges, a fantastic community along with companies like Nodejitsu helped Node grow into the success it is today. Now almost five years later, Nodejitsu and its team of Node.js veterans have a new path forward: we are joining the team at GoDaddy. We’ve been working very closely with GoDaddy over the last few months helping in their transition to Node.js and everyone at Nodejitsu was impressed with the transformation and big challenges they’re taking on to empower small businesses across the globe.

That’s the 10,000 foot view. I am an existing Nodejitsu customer.

What is a typical Message over HTTP Long Polling or WebSockets JavaScript Serialized Object Notation, or JSON, has quickly become the new standard in transferring information between applications, browsers and machines.
The cost of privacy. I have a bone to pick with a certain oddly prevalent piece of received wisdom in the JavaScript community.

I’ve been meaning to rant about this properly for what seems like geologic amounts of time, but I finally hit a concrete example today that both broke the camel’s back and gave me something I could actually illustrate my point with. Let’s talk about private variables, or more precisely, defining API methods inside a closure, giving them privileged access to data that code outside the closure cannot see. This is used in several JavaScript design patterns, for example when writing constructors or using the module pattern: The reason people use this pattern, in fact the only reason for doing so as far as I can tell, is encapsulation. They want to keep the internal state of something private, so that access to it is predictable and it can’t put the object in a weird or inconsistent state, or leak implementation details to consumers of the API.

Done!
